Permatex Fluids
See what we have from Permatex

RockAuto is excited to announce the addition of Permatex to our growing selection of automotive fluids. Since 1909, Permatex has been a respected leader in the development of innovative Gasket Makers, Sealants and Thread Compounds. Today, they manufacture one of the most advanced selections of premium automotive chemical products including Gasket Makers/Removers, Sealants, ThreadLockers, Adhesives, Cleaners (brake, throttle body...), Repair Kits (radiator, fuel tank...), Lubricants (battery terminal, engine rebuild...) and Rust Inhibitor/Remover.

Why use a Gasket Maker?
Using a Gasket Maker instead of a conventional gasket can save both time and money by allowing you to easily create the exact gasket you need. Permatex gasket makers are not only resistant to vibration, fluid and temperature cycles like traditional gaskets, but they can also eliminate leak paths and seal worn/uneven surfaces that traditional gaskets cannot.

What is a ThreadLocker?
A ThreadLocker, or Thread-Locking Fluid, is a thin adhesive that is applied to the threads of bolts and screws to prevent accidental loosening, leakage and corrosion. ThreadLockers are especially useful for connections that are subject to repeated vibration and strain or in situations where the connection point is intended to last long periods of time. Part manufacturers will sometimes include use of ThreadLocker in their installation instructions.

You can find Permatex Gasket Makers and ThreadLockers, as well as other Permatex products, in the "Tools & Universal Parts" tab under the different product categories.

Repair Mistakes & Blunders
Repair Mistakes & Blunders

It was 1981 and now that I was out of school, I finally got out of my old rust-bucket and into a newer car – a 1977 Volkswagen Scirocco. Having received tune-up lessons from a few good folks wiser than I, I confidently performed my own tune-ups. So it was the typical fall tune-up time, and the Scirocco had become tough to start. I proudly replaced the plugs, points, condenser, oil and filters. After setting the dwell and timing, sure enough, it started right up and ran smooth. The next morning on my way to work, I was at highway speed and all of a sudden, my Scirocco started misfiring and losing power. Moments later it was back to normal. The drive home was flawless. Hmmm...was it some bad gas?!

The next day, again at highway speed, it happened again. Engine misfiring and losing power for a few moments, then right back to smooth and normal. This was peculiar! It was not until a couple days later (each day experiencing the same temporary misfire) that I realized this phenomenon happened at the exact same place on the highway! Sixty miles per hour while doing a fairly sharp left turn. So that night I started digging around examining my previous tune-up work. Sure enough, there was the culprit – I neglected to tighten the nut that secures the condenser wire to the points. It was touching the points because of the spring pressure in the wire wanting to be straight. During that high speed left turn, the centrifugal force was just enough to pull the wire away from contacting the points, and thus created the misfire.

The lesson learned like so many of us have – double check that everything is tightened properly. Now when I torque a bolt, I use a marker to mark the head so I can easily see it has been done. This is especially important when you have a specific tightening sequence/steps such as a cylinder head or timing chain cover. A paint pen works well too!

EVAP or Other Trouble Codes
Tom's Story

In the past, it was always easy for me correctly diagnose fuel tank cap problems. My wife or I would accidentally leave the fuel tank cap sitting on top of a gas pump at a distant gas station, and when we got home, it was obvious we needed to buy a new fuel tank cap. Unfortunately, a tether prevented losing the original gas cap on my daughter's 2005 Ford Mustang. We needed its OBDII system to give us a clue that it was time to buy a new fuel tank cap.

The clue was the illuminated check engine light. My daughter and I got into a routine of hooking up a scan tool, reading a P0456 EVAP Very Small Leak trouble code and erasing the trouble code with the scan tool.

I knew that a leaky fuel tank cap was often the cause of EVAP problems, but as can be seen in the photo, the gasket on the old gas cap did not look too bad. There were no obvious tears or signs of permanent compression/distortion. I doubted the car's OBDII system could detect a miniscule leak from that nice looking gasket even if there was one.

Rather than throwing parts at the car, I thought I should wait until my daughter and I had time to methodically check all the hoses leading to and from the vapor canister and EVAP purge/vent solenoids. This EVAP trouble code can only happen when the fuel tank is between 1/4 and 3/4 full. I encouraged my daughter to fill up the fuel tank frequently.

Weeks passed without us finding the time to do any methodical EVAP checking. We decided it would not be so bad to throw an inexpensive new fuel tank cap at the car. After more than a year without any EVAP or other trouble codes, I am now confident that a new fuel tank cap was all the car needed!

In hindsight, it seems silly to waste time inspecting the gasket on a 10+ year old fuel tank cap. We know to automatically replace gaskets on thermostats, valve covers, oil filter housings, etc. when the part is removed just once. Over ten years, a fuel tank cap probably gets removed and reinstalled at least 200 times! It would be smart to replace a fuel tank cap as part of routine maintenance or at least not hesitate to replace it the moment an EVAP trouble code appears. Or, simply disconnect the tether and leave old fuel tank caps behind at gas stations every now and then!

Bill's 1970 Chrysler 300
Bill's 1970 Chrysler 300

This is our beloved 1970 Chrysler 300. We recently purchased it from the original owners with only 32,000 miles. After many years of storage in a barn, RockAuto had everything I needed to get the 300 back on the road. From brake components and wheel bearings, to belts and hoses, to air conditioning and gaskets, RockAuto had everything, including the hard to find parts!

We enjoy this car every chance we get with leg room to spare. 

Thank You!
Bill in California
